Amino sugar is very important in human joints. The full name of amino sugar is glucosamine, which is one of the most abundant monosaccharides in the human body. The content of amino sugar in articular cartilage is very high, which plays a key role in the synthesis of protein in articular cartilage matrix and is an important nutrient for the formation of chondrocytes. Gu adopted the formula of "high amino sugar+hyaluronic acid", which can supplement 1468mg of amino sugar every day, which is in line with the internationally recommended supplement. Adding proper "lubrication" to joints can naturally relieve joint pain. Hyaluronic acid, like amino sugar, is also an important component in joints, which can promote joint lubrication and reduce joint wear during exercise. In addition, it can also remove harmful substances in the joint cavity and reduce joint inflammation and pain. However, in the past, hyaluronic acid could not be supplemented by oral administration, and the lost hyaluronic acid could only be supplemented by injection. Gu Bili's formula of "amino sugar+hyaluronic acid" can not only supplement the nutrition of joint deficiency, but also adopt the patented hyaluronic acid embedding technology, which makes oral hyaluronic acid possible and can be said to be very convenient.
